Title: Improvements in or relating to typographic casting machines
IPC: B41B25/00
Filed: 1920-07-16
Abstract: 151,252. Lanston Monotype Corporation, (Assignees of Indahl, M. C.). Sept. 12, 1919, [Convention date]. Single-type composing and casting machines. - Positioning-mechanism for the die-case, mould-dimensioning mechanism, or other adjustable element of a type composing and casting machine such as that described in Specification 8633/99, which is particularly applicable to the multiple-blade mould described in Specification 142,545, comprises a series of signal-controlled stop-pins or the like and a co-operating selecting plate or member which is coupled with the member to be adjusted, the mechanism moving direct from one position to another without returning to a zero position. In the arrangement described, two rows of stop-pins 33<a>, 33<b>, Fig. 4, which are operated in pairs by signals in the record-strip, are located beneath a selecting slide 26 which is movable in either direction by aircylinders 25, Fig. 5. The slide contains two overlapping slots 37a, 37b into which the pins rise, the plate permitting only one pin of a pair to rise except in one position in which the same signal is repeated and no movement of the slide is therefore necessary. The slide is moved until the inner end of one of the slots engages the raised stoppin by the appropriate air-cylinder 25 to which air is admitted by a valve operated by one of two pivoted bars 38, Fig. 5, each of which overlies one row of stop-pins. The slide acts through rack-and-pinion mechanism to rotate a shaft 61, Fig. 9, which is connected by screw-and-nut mechanism 65, 66 and a lever 68 with the mouldblade selecting slide 16. Since the slide 16 can only be adjusted when the mould-blades are in closed position, and the impulses due to the record-strip signals occur earlier, the actuated stop-pin is maintained in raised position by one of a set of detents 45<a>, Fig. 4. The admission of air to the cylinders 25 is controlled by a valve operated at the required time by a cam. A second cam operates a slide to release the detents 45a.

Abstract: 481,502. Colour kinematography. BERAN, P., and OBERER, F. Aug. 5, 1936, No. 21605. Convention date, Jan. 21, 1936. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 6, 1937.] [Classes 97 (i) and 98 (ii)] The two filters employed for the exposure of a single film are different in colour from and more pervious to light than the projection filters. The exposure filters may be respectively yellow-green and red-yellow and the corresponding frames of the positive may be coloured light blue and yellow brown. The film may be coloured throughout with a blue dye and then alternate frames coloured, e.g. by rolling with a yellow-brown dye. Alternatively the entire film may be coloured with a red dyestuff (Victoria Rubino), each alternate frame then treated with ammonium or potassium bichromate and exposed to light to tan the emulsion. The film is then washed in water containing a little acid or alkali thus releasing the red dye from the untanned frames, and the film is then treated with a blue dye (Cyanin B) which lodges only in the untanned frames. In a modification the whole film may be treated with a mixture of the red dye and the bichromate, exposed in alternate frames and then washed and redyed as before. According to the Specification as open to inspection under Sect. 91 instead of redyeing the film, the original dye may be such as can be converted to a red or blue colour after exposure and fixing of alternate frames. Suitable dyes are litmus, Congo red, haematoxylin, indigo white or indigotin, the converting reagents being hyposulphite solutions, dilute acids, ammonia or other alkaline solutions. As a guide for the correct setting of the film for projection, alternate frames are provided with a mark at the time of exposure for example by a small electric bulb carried by the camera. The document also describes a shutter comprising discs 1, 2, having registering apertures c<1>, c<2>, d<1>, d<2> and relatively rotatable to adjust the exposure. The apertures c<2>, d<2> may carry the removable colour filters. This subjectmatter does not appear in the Specification as accepted.

[Also in Groups XI and XXXVI] In fused-electrolyte apparatus previously-baked carbon slabs 4, Fig. 1, are connected to metal busbars 5 by means of cast iron 6 which has a melting point above 1000 C. and is practically free from any constituents liable to undergo transformation accompanied by an increase in volume by prolonged maintenance at a temperature of 900 C. The castiron may contain combined carbon 0.2 to 0.5 per cent, free carbon 2.8 to 2.5 per cent, silicon 2.5 to 3 per cent, phosphorus 1 to 1.5 per cent, manganese less than 0.5 per cent, sulphur less than 0.05 per cent. The bars 5 are fixed in grooves in the slabs which are preferably heated before the sealing operation, and the molten metal may not only fill up the spaces in the grooves around the bars, but may also form flanges 6a, Figs. 6 and 7, at the bottom of the slabs and flanges 6b at the sides. Fig. 8 indicates a method of securing a metal bar to three carbon slabs. The slabs are turned upside down and held together by a casting frame 10. Joints 9 of asbestos and sand separate the grooves 7 in each slab while the metal is being poured in, the joints and frame 10 being removed as soon as the metal surface starts to solidify. The slabs are sealed simultaneously. When the bar 5 is secured to a single long slab, the space into which the metal is to be poured is divided into portions filled separately, with the middle section or sections being filled first, in such a way as to avoid an unsealed section between two sealed sections. Considerable time elapses between filling of the different sections. The Specification as open to inspection under Sect. 91 also comprises the use, instead of cast iron, of copper, bronze, or any other suitable metal. This subject-matter does not appear in the Specification as accepted.

Abstract: A heat-polymerizable monomer is polymerized by mass or emulsion methods at a temperature of from 20 DEG  to 125 DEG  C. in the presence of a preformed copolymer of a mono-olefinic aromatic compound and a lower aliphatic mono-olefinic compound containing 2 to 8 carbon atoms, which is soluble in the monomer and has an intrinsic viscosity in toluene of at least 0.5 and a sufficient combined aromatic constituent to render it compatible with the polymer produced but not so high as to prevent it having a plasticizing effect.  The monomer may be styrene, p-methyl-, p-chloro-, p-bromo-, 2-chloro-p-methyl-, 2,4-dichlor-, 2,5-dichlor-, 3-methoxy-, 4-methoxy- or 4-phenoxystyrene, indene, vinyl naphthalene or dihydronaphthalene, butadiene, mono-olefinic unsaturated alcohols, ethers, esters, acids and hydrocarbon halides, e.g. vinyl chloride or acetate, vinylidene chloride, methyl methacrylate, lauryl methacrylate, fumarates, methylacrylonitrile or acrylonitrile.  The preformed copolymers are of styrene, a -methyl, p-methyl-, a -methyl-p-methyl-, 2,4-dichloro-, p-chloro-, a -methoxy-, or 2-chloro-p-methyl-styrene, vinyl naphthalene, indene or dihydronaphthalene, with isobutylene, methyl-2-butene-1, propylene, isooctene or ethylene and, if desired, a third reactant such as isoprene, butadiene, divinyl benzene, 2-methylpentadiene, cyclopentadiene, myrcene, alloocimene and 2,3-dimethyl butadiene-1,3, in such proportion that the copolymer contains at least 85 per cent of mono-olefinic material.  The copolymers are prepared in the presence of a Friedel-Crafts catalyst below - 50 DEG  C., preferably in the presence of a C1-C4 alkyl halide solvent, and are dissolved in the monomer, which is polymerized by a mass reaction using benzoyl peroxide or by an emulsion method using soaps, e.g. sodium stearateor oleate and catalysts such as potassium per sulphate.  Examples describe the preparation of a styrene-isobutylene copolymer and its use in the mass polymerization of styrene with benzoyl peroxide catalyst, and in the aqueous emulsion polymerization of vinyl chloride, styrene - acrylonitrile, and styrene - butadiene; and the use of p-chloro-styrene-isobutylene copolymer in the polymerization of vinyl chloride.  The products may be compounded with pigments, other resins, wood flour, wax or clay, if desired, to form sheets or films, which may be cured.
